Dwelling automation programs are all effectively and good, as long as the one who constructed all of it is round to drive it. Let’s face it, they’re very often a fancy internet of interconnected programs, all tied to the specifics of 1’s house — and somebody much less accustomed to all of it may get slightly irritated if, on a cold day, the interface to the boiler is by way of a Python script, and one thing received’t work. Simply saying. Home Buttons by [Matej Planinšek] over on Hackaday.IO is a properly polished venture, which goals to take among the hackiness out of such automation by offering a smooth entrance finish to these automation routines, enabling anybody to rock on over and set one in motion with out problem.

Internal PCB shown in the foreground, with the complete unit behind.The PCB relies across the ESP32-S2-mini which offers with WiFi connectivity and integration with Dwelling Assistant utilizing the standard MQTT protocol. We count on integration with different flavors of house automation wouldn’t be troublesome to realize. The middle of the unit holds a easy E-Ink show, for that low-standby energy. Particularly, the unit chosen is a Good Show GDEY029T94 2.9″ which this scribe can affirm is simple to interface and fairly low cost to buy from the standard Chinese language on-line distributors. This was matched up with six clicky Alps SKRB-series low-profile tact switches, which sit on both facet of the show, and corresponds to a flexure-type affair on the 3D printed entrance casing. Neat and easy.

The PCB design was offered in Altium format, which you’ll find on the project GitHub page. This reveals an easy design, with a couple of good little particulars right here and there. The internally mounted 18650 cell is reportedly good for at the least a yr of operation, however when time, it may be charged by way of USB. A Xysemi XB8608AF (PDF) safety chip gives applicable limiting for the 18650 cell, shielding it from the perils of overcharging, discharging, and whatnot. Not that that’s seemingly on this present setup. A Sensiron SHTC3 humidity and temperature sensor can also be in there, hanging off the I2C bus, which is sensible for this utility.

Dwelling Automation hacks are a lot on these pages, like this scroll-wheel interface, for example. If all these things is trying fairly overbearingly sophisticated to get into, how about beginning with a Pico W?
